Yale-led study finds ozone-related deaths likely to rise if the world fails to meet the Paris Agreement

Failure to limit the global temperature increase means ground-level ozone mortality will rise dramatically, researchers predict.

Eight ways chemical pollutants harm the body

E-Mail
A new review of existing evidence proposes eight hallmarks of environmental exposures that chart the biological pathways through which pollutants contribute to disease: oxidative stress and inflammation, genomic alterations and mutations, epigenetic alterations, mitochondrial dysfunction, endocrine disruption, altered intercellular communication, altered microbiome communities, and impaired nervous system function.
The study by researchers at Columbia University Mailman School of Public Health, Ludwig Maximilian University, and Hasselt University is published in the journal
Cell.
"Every day we learn more about how exposure to pollutants in air, water, soil, and food is harmful to human health," says senior author Andrea Baccarelli, MD, PhD, chair of Environmental Health Sciences at Columbia Mailman School. "Less understood, however, are the specific biological pathways through which these chemicals inflict damage on our bodies. In this paper, we provide a framework to understand why complex mixtures of environmental exposures bring about serious illness even at relatively modest concentrations."
